Very low CPU usage and MAXing out one thread

[pappalitto 10]

I have a 5820k and my 980ti is barely being ultilized.  With this new graphical update no hardware on earth could run it at a decent frame rate if it doesn't use your computation.  I would love to see this addressed in a dx12 update the the LOAD IS ACTUALLY ON THE GPU.  Also, in the dev build the A-164 main cannon's sound often cuts out in the cockpit

normal behaviour. this games has always smashed one thread for most of the simulation, and only the newer stuff introduced in arma 3 such as PhysX and rotorLib are operating in seperate threads. DirectX usually uses its own thread to feed the video card, even then it doesn't push it too hard since many calculations such as shadows are still calculated in that one dinky little thread running everything else. DX12 is not the be all end all, unless of course your game is using many draw calls or was being bottlenecked by the directX 11 API, which is definately not the case for RV4 and arma 3.

 

so what is the issue exactly? poor performance compared to stable? or just more ranting about how your strong cpu and gpu don't get you good performance?

Yeah thats ArmA, you will rarely use more than the equivalent of 2 cpu cores, that´s why higher clocked i5's are better than i7's like 5960X.

 

dx12 to be properly used would need a massive engine rewrite, simply slapping it on top would change very little.

By default a 5820k runs at 3.3 GHz. Which is fairly fast but certainly not fast enough to keep up with a 980 Ti (your PC is unbalanced). So if you want to remove the bottleneck, then overclock your 5820k. You should be able to reach 4.0 GHz easy, 4.1 prolly, 4.2 maybe adn 4.3 if you're lucky.
